The elements are all mounted on independent parallelograms, inter row by row, with sealed ball bearings for optimal stability. The working depth is set by crank handle. During hoeing, a ball bearing gauge wheel manages the depth. The leaf protectors are light and articulated on a parallelogram
for a better monitoring of the soil surface, a good footing on the ground and respect for the roots of beets. For a better longevity, a shoe protects against stones.
